Lastly, addition of our new Co-Investigator Biostatistician, and IT/Database expert, elevates the effectiveness and visibility by which we can conduct power analyses, share data, manage and access joint databases, and increase both qualitative and quantitative inter-project communication and peer-reviewed articles over the next 5 years.
